Finally getting rid of the junk battery that came with my boat last year. I currently run 2 power poles, 2-12” lowrance carbons, Yamaha 250 sho and aerator all day(crappie fishing). Some days if it is windy I will move the poles up and down quite a bit(drift paddles). Am I better off to get one good 31 agm to run all of this or to run two lighter/smaller batteries in parallel? Trying to weigh out the pros and cons before purchasing...
